To all whom it may concern Be it known that I, CHARLES W. WooDsoN, acitizen of the United States, and a resident of Portland, county ofMultnomah, State of Oregomihave invented certainnew and usefulImprovements in Harvesters, of 4which the following is a specification.V

My invention relates to harvesters in general, and particularly to suchharvesters as are adapted to the harvesting of beets and the like.

The object of my invention is to produce a device that willv low thebeets from 'the ground, remove t e tops-thereof, and deposit the topsvand the beets in separate rece tacles.

accomplish the above object by means of the construction illustrated inthe accompanying drawings, which are a part of this application forLetters Patent, like characters of reference indicating like partsthroughout the several views thereof, and in which; I l,

Fig. 1 is aside elevationof my device.

Fig. 2 is a plan view of my device, the seat and operating levers beingremoved therefrom.

Fig. 3 is a side elevation of the oscillating frame, upon an enlargedscale.

oF ig. 4 is a plan view of the subject matter of Fig. 3.

Fig. 5 is a sectional view upon line 5 5 of Fig. 4. L

Fig. 6 is a sectional view upon line 6 6 of Fig. 1.

Fig. 7 is a perspective View of one of the shaft boxes.

Fig. 8` is a perspective view of one of the chain bearing strips.

In general my invention consists of a wheeled vehicle whereon aremounted suitable plows for removing the beets from the ground, means toclutch said beets by the tops thereof and carry the same to suitableknives Whereat the beets and the beet tops f are severed, elevators toreceive the beets and the beet tops and carry the same to separate bins,and means to adjust the various parts suitably for the work.

The vehicle consists of a traine 9, to the iii-dnt end ot' which ispvotally attached the front axle l0. Means to propel the vehicle are tobe attached to said axle l0, and the ordinary horse pole and equulizersare most suitable.

Pivotally attached so the front member of ftheframet): are a pair-ofbent arms 11,

eachof which arms carriesat its lower vend a suitable plow g 12, said.plows` adaipted to work upon opposite sides of a row of beets l0 to.remove the same from .the ground.

To adjust the .relation of saidy plowsV 12 vto the ground I provide alever 13 withI a latch thereon suitable for engaging notches upon aquadrant 14, said lever having there.- u

`on an arm 15 connected by a link 1 6 to'a. oros pin 17 between saidchains 18 move in longitudinal slots in said frame, the adjacent?portions of vsaid chains immediately rearward of the lplovvs' 12traveling in the s ame'direction and at 80 the same speed, and beingbaoked'iip b l"the oscillating Aframe so that thfe spa/.e betweenremains substantiallyi constant, and just suiicient to retainythe beettopsbetween the adjacent chain portions. j

' To sever the beets from their tops'l proa vide topping knives,preferably circular, as shown, at 21, one of said 'knives being'se!4cured upon each of the shafts of s 20, and the peripheral edges of said)'ves 90 being` sharpened and practically in"contact"' with each other. y

In order to raise the beets from the plows, the slots in which'thechains 18 operate are given an inclinedposition, and the pper portionthereof curved for the purpose of delivering the beets properly to theknives 21, as shown in Fig. 1. j l

The knives 21 are immediately below the sprockets 20, and to adjust thesaid knives vertically relatively to said sprockets for the purpose oftopping the beets clean I provide that each of said knives may be raisedor lowered upon the sprocket shafts 22 of sprockets 20, and secured inposition thereon by set screws, as shown in Fig. 1.

To receive the severed beets'and beet tops I'provide respectiveelevators therefor, each elevator being pivotally7 upon the oseillatinframe rearward of the-knives 21, eachpf sai elevators consisting of sidemembers 2,8, supporting rods 24, sprockets or pulleys 25 with 'iooendless iiexible `menfoers y,or belts/thereon.

vv'The elevatoil adapted to -ie'ceive beet tops is` disposed immediatelyabove that adapted to receive the severed beets, the formerfbeingrovided withv slatsQZ, or the like, suitable or retaining ...he'beettops upon their respective elevatoi'-niembers 26, and the latter ,beingrovided with -buckets 28, orA the. like, suitab e for receiving thebeets and retaining;` them upon the elevator members 26.

Real-ward of said elevators, and below the discharging ende thereof, ,I'provide suitable respectlve bins oir-receptacles 29 to receivev the`material therefrom. yin' orden that the contents of said .bins maybexdumped frein time tok time I provide thereforv hinged bot'- toms 30,eacb'connecte'd bya lever 3l and reach lrod `32 to one end/of a lever33, said level` 33 having thereon a catch `adapted to` engage suitablenotches in a quadrantfi.

` To drive the various mechanisms just de-4 scribed I provide acrossshaft 35 mounted upon i frame membersy 9 and connected to one of therear'wheels 36 of the, vehicle by preferably chains, ai operating oversuitable y means of a drive chain 37 shown in Fig, 2. H g Each of thesprocket shafts 22 is driven from the cross shaft by means of bevel ears39, and thus chains 4ldaad the' ives 21 are operated.

The supporting rods ofthe elevators are pivotally mounted upon thelcross shaft 35. Thus vthe entire apparatus, including the chains 18,knives 21, and both elevators are mountedy oscillatinglyabont shaft 35by means of an roscillating frame illustrated in ,elevator for the beettops .and to the lower elevator for the'beets.

This frame contains suitable bearings 4]. to receive cross shaft 35, andalso suitable; bearings 42 and 43to receive the sprltet shafts 22.Rearwaidly ydisposed bearings 44 and 45 are provided respectively forthe foot shafts 46 and 47 respective. to the upper'l The rearward endoi.2 the oscillating frame is rectangular in shape, and pi'ovided'withan inclined bottom 48, the sides of the 'frame a'nd said bottom forminga lhopper or Ie ceptacle beneaththe knives 2l` into.' which the severedbeets diop,and fioinwhich said severed beets are removed by the lowerele-v vator and Abuckets '28, vto be deposited in their respectivev bin29. f' .A partitionorfshelf 49 is `providedin the rearward end of theoscillating frame, dis-.

y ,Lacasse fshelt' said beet tops are removed by the up` theii`respective bin 29.

The` forwaigd end of the per elevator and slats 27, tobe deposited in yh V oscillatingr frame consists of a` pair of downwardly inclined arms50,.,the forward ends-of which are forked to receive sprocketsl, andeach of l said forked ends is provided with transverse slots. orrectangular orifices 51 in which` arey Slldably mounted' suitable boxes53 as bearings Afor the spiocket shafts 52,01 sprockets Each of saidboxes is pi'ovided with a guide 54 adapted 5to"` slide tifansveisely,within its 'respective oriicel, and collars 55 are provided upon eachsh'aft52 to secure Springs 56 connect.adjacent pairsotl said boxes rasshown in Figs.` 2 and 6, the purpose of said springs being to'secure aproper relative vclose adjustment of the chains 18,

and to provide that said. chains `may sepaateA between.' y

The chains 18 are guided-in their movement by slots 57 inthe armswdandIto pron vide a yieldable `relationship between the should any excessivebulk be deposlted there- 4 chains ,18" as they move 'earwardly from theysprockets 19 lyprovide in the adjacent 'slots 57- weaiing strips '58seach adapted to Contact with its respective chain 18, said ,wearingstrips beingl forced towards eachother v by springs 59 in pockets 60upon arms 50.
